Suspects `filmed New York atrocities'

There are reports five men suspected of being involved in the attack on the World Trade Centre set up cameras to record the atrocity.

The men set up cameras by the Hudson River and trained them on the twin towers.

The New York Times reports they congratulated each other when the crashes occurred.

The five are under investigation by police in Union City, New Jersey, but it is unclear if any of them are in custody.

The allegation came as police in New Jersey told the New York Times the hijackers who left from Newark airport on the flight which crashed in Pennsylvania had received aid from associates in the area.

The paper reported law officials said the team was "aided by confederates in Newark who were responsible for logistical support, including money, rental cars, credit cards and lodging".

And it emerged that FBI investigators believe each team of hijackers acted independently from each other but under orders from a supreme commander.

The conclusion was reached after evidence from the flights' passenger lists, payphone records, evidence taken from the rental car seized in Boston and the frantic phone calls made from the hijacked planes.

It was the commander who selected the flights to be hijacked and orchestrated the attacks to occur at about the same time.

But the man has not been publicly identified by investigators, the New York Times reports. His whereabouts are currently unknown.
